Abstract EN
Background : The bond strength of root canal sealers to dentin was important for maintaining the integrity of the seal in root canal filling in both static and dynamic situations.
In a static situation, it should eliminate any space that allowed the percolation of fluids between the filling and the wall while in a dynamic situation ; it was needed to resist dislodgement of the filling during subsequent manipulation.
Materials and Methods : Forty mandibular premolars were selected for this study.
All canals were instrumented using ProTaper rotary instruments.
Instrumentation was done with copious irrigation of 5.25 % sodium hypochlorite.
Roots were randomly divided into four groups according to the type of cleaning and method of root canal irrigation (ten teeth for each group) : Group A.
The root canals were irrigated with 5 ml of 17% of EDTA for 1 minute and 5 ml of 5.25 % NaOCl.
Group B.
Cleaning with waterlase laser.
Group C.
The root canals were irrigated with 5 ml of 5mg / ml of siwak (Salvadora persica) extract for one minute.
Group D.
The root canals were irrigated with 5 ml of 5 % of green tea (camellia sinensis) extract for one minute.
All groups were rinsed with distilled water and then obturated with cold lateral condensation technique and i Root sp sealer (Bioceramic sealer, the roots then stored in moist environment at 37°C for one week.
Three horizontal sections were prepared at a thickness of 1 mm ±0.1 in the apical, middle and coronal parts of each root.
The test specimens were subjected to the push-out test method using a Universal Test Machine that carried 1-mm, 0.5- mm and 0.3-mm plungers for coronal, middle and apical specimens, respectively.
The loading speed was 0.5 mm / min.
The computer showed the higher bond force before dislodgment of the filling material.
These forces were divided by the surface area to obtain the bond strength in MPa.
Results : In all groups the mean value of push-out strength was greatest in apical area and least in coronal area and the middle area was in between, except in Waterlase the middle area showed the least mean push-out strength.
Conclusion : Herbal extracts used in this study (Siwak and green tea) can be used safely as an intra-canal irrigant for smear layer removal with efficiency that is comparable with conventional synthetic materials (EDTA) and more complicated methods (Waterlase).
